Answer:
B or C
Step-by-step explanation:It ain´t easy
The slope of the given line = 1 so the slope of the line perpendicular to it will be -(1/1) = -1.
It also passes through point (1, -1) so we use the point slope equation
y - y1 = m(x - x1)
y - -1) = -1(x - 1)
y + 1 = -x + 1
y = - x <--------- that's the answer
Answer:
198 m³
Step-by-step explanation:
Find the area of the triangular prism.
3 × 4 × 1/2 × 9
= 54
Find the area of the rectangular prism.
4 × 4 × 9
= 144
Add their areas.
144 + 54 = 198
The area of the composite shape is 198 m³.
